Hook Name : pre_enter_room
Called From : /obj/living/movement.c
Resolution Method : HOOK_OR
Sample Header :
int my_pre_enter_room(string tag, object ob, object who, string dir,
object src, int test)
Arguments :
tag - "pre_enter_room"
ob - The room being entered
who - The living object moving
dir - The direction being moved ("north" for example)
src - The room object being moved from
test - If 1, just check the validity of the move, don't print any errors
or cause any other side effects
Return Value : 1 to intercept the move, 0 to allow it
Description :
When a living thing attempts to move (either on its own, or being forced by
a spell or something else), this hook is called in the room they're trying
to move to.
If 1 is returned, the move is disallowed, and no messages are displayed,
so you should take care of that yourself. If 0 is returned, the move is
allowed (unless someone else had a give hook that returns 1).
Note also that if "test" is 1, no mesages should be displayed or side effects
carried out; simply return 0 or 1 like you otherwise would.
